To understand more concretely what effects Global Warming may have on life on Earth, Stager takes us back to the Eemian Interglacial, the most recent episode of Global Warming.
In fact, the fossil record suggests that it was during the Eemian Interglacial that a modern form of our species evolved and spread from the Rift Valley south to what is now South Africa and north to the Middle East.
When considered in the context of very warm periods in the distant past--such as the Eemian interglacial
, 130,000 years ago, when temperatures were perhaps 3[degrees]C warmer than they are today--the greenhouse warming that we're currently experiencing may not seem so outlandish.
A notable example is the Jaslo-Sanok Depression, where the highest rate of neotectonic uplift was documented in the Lublin (Schoningen, mid-Saalian) warming in the south, in the Zbojno Interglacial (Reinsdorf, early Saalian) in the north, and in the Eemian Interglacial in the east (cf.
Baumgart-Kotarba (1978), in turn, assigned the last episode of faulting in this region to the Eemian Interglacial.
The researchers, who evaluated geochemical and pollen analyses of lake sediments in Saxony-Anhalt, Brandenburg and Russia, determined that in Central and Eastern Europe, the slow ransition from the Eemian Interglacial to the Weichselian Glacial was marked by a growing instability in vegetation trends with possibly at least two warming events.
The Eemian Interglacial was the last interglacial epoch before the current one, the Holocene.
In conclusion, the samples examined here provide the following insights: (1) the absolute ages and stable isotope records of the Cueva del Cobre speleothems locate the onset of the Eemian interglacial as early as ~ 151149 ka BP, an age comparable to those provided by other palaeoclimate records from Northern Europe and North America, but notably younger than the age calculated by the Milankovitch theory; (2) our U-Th datings for these speleothems also give a precise age for the first time in Spain for the end of the Eemian interglacial (isotopic shift at ~115 ka; stop of speleothemic growth at ~108 ka); and (3) these U-Th ages reveal a consistent anomaly at ~105-100 ka BP, which could be related to a drastic climate change during the interestadial MIS-5c.
